Modern science believes that our universe was born 13.8 billion years ago, and 13.8 billion years ago, there was a singularity that exploded. The size of the infinitesimal point, after the explosion of this point, our universe rapidly expanded around, after 13.8 billion years, the universe expanded into what we see now, the celestial bodies in the universe are formed after the Big Bang, our earth is a planet in the solar system, there are a total of eight planets in the solar system, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, there is also a Pluto outside Neptune, once Pluto was also a planet, but later scientists thought that Pluto was too small in size and mass, so they kicked it out of the ranks of planets. Of the eight planets, Earth is the only one that has given birth to life.
The emergence of life has added a lot of color to the earth, especially after the emergence of human beings, the earth is a lot of mysteries, human beings as the most intelligent life on the earth, since the birth of the continuous research and exploration of the mysteries of the world, now human beings have a general understanding of the world, at present human beings have been able to go out of the earth to explore the universe, which shows that the speed of human science and technology development is very fast, when human beings out of the earth to know the vastness of the universe, human beings want to know how big the universe is? Is there still extraterrestrial life in the universe? With these questions, human beings embarked on the road of exploring the universe, in order to explore the mysteries of the universe, scientists have launched many probes, among which the farthest probes are Voyager 1 and 2, in September 1977, NASA launched a space probe weighing 722 kilograms, after the Voyager 1 probe was launched, with the dream of human beings to explore the universe, why choose this time to launch?
In fact, this launch made use of a special planetary alignment phenomenon, which is an astronomical phenomenon in which multiple planets in the solar system are aligned in the same straight line. When these planets are aligned in the same line, their gravitational interactions can have some special effects in the solar system, the appearance of planetary alignments is very rare, usually only once every few decades, the most famous planetary alignment was on March 10, 1982, when Venus, Mercury, Jupiter, Mars, Saturn were all lined up in a line, and in late 1970, Jupiter, Saturn, The position relationship between Uranus and Neptune has formed a phenomenon of planetary alignment, NASA took advantage of this opportunity to launch the Voyager 1 probe and the No. 2 probe, using the gravitational slingshot effect to reach the destination faster, the gravitational slingshot effect is a means of using the gravitational force and rotation speed of the celestial body to accelerate the spacecraft, when the probe enters the gravitational field of the celestial body, it will be attracted by the gravitational attraction of the celestial body, but at this time the celestial body is in a state of rotation and revolution.
Suppose Jupiter's orbital speed is about 13 kilometers per second, so the probe will be carried by celestial bodies in its orbit for a period of time under the influence of gravity. When it leaves the planet's orbit, it will get the planet's acceleration to it, which will allow the probe to accelerate forward, and scientists at that time installed a gold record on the Voyager 1 probe, which is different from our ordinary record. In order to be able to resist the extremely low temperature of the solar system and various radiation in the universe, NASA uses copper materials when installing gold records, which is equivalent to plating a layer of copper on the surface of the records, so that the service life of gold records will become longer. And on this gold record, scientists burned the location of the earth, the sounds of animals, the voices of humans, the sounds of nature, and so on.
Scientists believe that if Voyager 1 and Voyager 2 can be lucky enough to fly out of the solar system, maybe the alien civilization will be able to discover them, and if the alien civilization discovers them, the alien civilization may be able to find the earth according to the information above. At that time, scientists also considered this problem, so when scientists made the gold record, they used the most common hydrogen element in the universe, and used this element to invent a kind of secret key, and the picture in the lower right corner of the gold record illustrates the transition diagram between the two lowest states of the hydrogen atom, and scientists believe that any kind of civilization with astronautical capabilities can see the information on it.
In the upper left corner of the disc is the binary code, the vertical line is the binary 1 horizontal line is and the binary 0 indicates that the performance speed based on the hydrogen clock is 16.667 revolutions per minute, and the binary code below indicates that the playing time of each side of the record is about 1 hour, when the gold disc is played, any civilization can understand the content on it, after everything is done accurately, on September 5, 1977, the much-anticipated Voyager was launched, at the beginning of the launch of Voyager 1, communication technology was still relatively backward. However, radio and communication technology has made tremendous advances over the past few decades. Earth's deep space communications network continues to grow, including NASA's deep space network, major observatories, and the support of international cooperation organizations. These facilities are equipped with highly sensitive antennas and receiving equipment capable of capturing Voyager 1's weak signals, decoding and processing them. The Voyager 1 probe carried a sophisticated and powerful set of communication equipment. It is equipped with a low-power transmitter to send signals to Earth.
At the same time, receivers on Earth used high-gain antennas and sensitive receivers to capture and decode the signals sent by Voyager 1. This powerful communication device makes it possible to maintain communication even at extremely long distances and with weak signals. During its flight, Voyager 1 sent back a lot of very important information to mankind, and when it approached Europa in March 1979, it photographed the presence of active volcanic eruptions and warm underground oceans on Europa, a discovery that changed scientists' understanding of the ice satellites of the solar system and laid the foundation for future satellite exploration missions. Passing by Saturn in November 1980, the Tretton Fountain above Titan was discovered for the first time, a column of spray made up of ice particles and water vapor ejected from Titan's South Pole, a discovery that revealed evidence that Titan may have an underground ocean. It has also aroused the interest of scientists in exploring the existence of life on other celestial bodies.
In 2012, Voyager 1 entered interstellar space, becoming the first probe in human history to leave the solar system, it continued to fly away from the sun, transmitting information about the external environment of our solar system, Voyager 1 is the first probe in human history to successfully leave the solar system, its departure marks mankind into the era of interstellar space. This is a landmark feat that demonstrates to the world the scientific and technological prowess and spirit of exploration of mankind. Voyager 1 collected a vast amount of data and images during its flight, providing scientists with valuable information about the outer environment of the solar system. Its detection results have changed our understanding of planets, moons, comets and other celestial bodies, and provided important clues to the origin and evolution of the universe. The achievements of Voyager 1 have sparked the enthusiasm of scientists and researchers around the world. Its success has inspired more exploration missions and scientific experiments, and promoted development and breakthroughs in the field of science.
Voyager 1 was followed by Voyager 2, in 1979, Voyager 2 successfully reached the orbit of Jupiter, and the Great Red Spot on its surface and the surrounding satellites were explored and photographed, on February 24, 1986, Voyager 2 flew less than 80,000 kilometers from the clouds of Uranus, realizing the first human exploration of the planet, Voyager 2 collected the planet's unique atmosphere, Magnetic field and ring data, on August 25, 1989, Voyager 2 flew by Neptune at close range, and explored Neptune, Voyager 2 sent back a lot of precious information to mankind, so that human beings know the basic situation of Saturn, Jupiter, Uranus, Neptune, and discovered the unknown ring of Neptune, during the observation, Voyager 2 also observed a major event in the solar system - Shoemaker-Levy Comet impact Jupiter. In July 1994, scientists around the world focused their eyes on Jupiter.
Because at that time there was a comet called SL9 was hitting Jupiter, in just six days, Jupiter was hit 21 times by the comet's fragments, producing a plume of up to 3,000 kilometers, the power generated by this impact, equivalent to the energy of 300 million atomic bombs, when the comet hit at a speed of 60 kilometers per second, the largest debris reached 2 kilometers, this impact reminded scientists of the scene of the asteroid hitting the earth 65 million years ago, when an asteroid with a diameter of 10 kilometers hit the earth, causing 90% of the life on the earth to be wiped out, and the overlord of the earth at that time was the dinosaurs, Dinosaurs ruled the earth for 160 million years, if it weren't for the impact of the asteroid, maybe the dinosaurs are still alive, after observing this impact, Voyager 2 also flew towards the outer solar system, and in interstellar space, Voyager 2 encountered a high-temperature wall of fire, this mysterious wall of fire has a temperature of up to 40,000 degrees Celsius.
In the process of the probe passing through the wall of fire, it detected a sudden increase in the number of charged particles, the energy of these particles is very high, and the speed is also very fast, the discovery of this phenomenon provides mankind with an understanding of the solar wind and the solar magnetic field. Scientists believe that temperature is actually the kinetic energy of the vibration of the particles that make up the matter, the more intense the particle vibration, the higher the temperature will be, but when the particles are thin, the heat is very low, just like the same temperature of water and water vapor, the heat brought to us is different, which means that the smaller the density, the smaller the heat, in 2018, scientists launched the Parker Solar Probe, the design temperature limit is less than 2000 degrees Celsius, but the temperature of the solar corona has reached 2 million degrees Celsius.
Parker Solar Probe is able to pass through its own temperature value up to 1500 degrees Celsius area, mainly because the density of particles is very low, even if the temperature is high, but its heat is very low, scientists have found through research that in the interstellar space of 18 billion kilometers from the earth, the density of matter is very low, the number of particles gathered together is very small, so it cannot form a barrier with strong resistance, Voyager 2 actually bears a small thermal impact, which is equivalent to a foam wall, so it is easy to pass through, but in the process of Voyager 2 flight, there are also some small problems, in its area of 18 billion kilometers from the earthThere are many people who believe that it may be an extraterrestrial civilization that has tampered with its program, and that extraterrestrial civilization is an extraterrestrial civilization that human beings have been looking for since they left the earth, and scientists believe that since the planet Earth can give birth to life, then other planets in the universe must also be able to give birth to life.
As long as the basic conditions for the birth of life can be met, then the possibility of the birth of life will be very large, in the vast universe, the number of planets and stars can not be counted, and the earth is only one of them, so scientists believe that there must be an alien civilization in the universe, and the level of alien civilization may be stronger than human civilization, after all, human civilization has only developed for thousands of years, and alien civilization may have developed for hundreds of millions of yearsAt that time, NASA scientists sent instructions to Voyager 2 about the probe to rotate 360 degrees and calibrate the onboard magnetic field instruments, although the communication between Voyager 2 and Earth was not timely, but generally did not exceed 17 hours, and strangely, after 24 hours, Voyager 2 did not follow human instructions.
This is the first time in more than 40 years that Voyager 2 has rejected a human command, because Voyager 1 and Voyager 2 are powered by radioisotope thermoelectric motors, and the energy to maintain the normal operation of the spacecraft comes from these radioactive isotopes, such as plutonium-238, which will convert the heat emitted into electricity when it undergoes radioactive decay, and then provide it to the spacecraft. But as time goes by, the spacecraft will consume more and more energy, which will greatly reduce the spacecraft to receive and transmit signals and power, and this abnormal refusal caused Voyager 2 to delay this mission for a period of time, and this delay directly caused the energy consumed by the two on-board magnetic field instruments to skyrocket, almost exhausting the original little power left. Originally, Voyager 2's capacity reserves were expected to be able to be used until 2030, and then the Youhe decay battery would work, but with the current situation, Voyager 2's death rate may be accelerated, and once Voyager 2's energy is exhausted, it will become a pile of space junk, floating in the universe forever.
Although the life of the Voyager 1 and 2 probes is coming to an end, they have played a key role in human exploration of the solar system, and the data transmitted by these two probes has made human beings have a new understanding of the solar system. In order to keep Voyager 1 stable during long flights, scientists equipped it with a parabolic dish antenna with a diameter of about 3.7 meters. This antenna uses the frequency of the S-band and X-band to modulate the radio signals sent on the earth, so that the interference that occurs during the communication process can be controlled to a minimum, so as to ensure the reception and transmission of information. As an unmanned probe in the outer solar system without backup support, in order to maintain communication, it is not enough to have good equipment, but also enough energy to support the operation of the equipment, and the energy for Voyager 1 is three radioisotope generators.
In order to save power as much as possible, scientists began to turn off the cameras on Voyager 1 from a very early age, so the radioisotope generators on them can ensure that they can communicate with the earth for decades, but this alone is not enough, after all, to receive such a distant signal, so NASA has begun to prepare 10 years before the launch of the Voyager 1 and 2 probes, NASA has built a huge tracking and control network on the ground, as far as possible to eliminate communication blind spots, so that the information can be transmitted back smoothly, but unfortunately, the battery power of Voyager 1 and 2 is about to run outThese two probes will also be completely out of contact with humanity, and they will remain in the solar system forever. The solar system is much larger than we think, before scientists thought that the edge of the solar system was on Pluto, but now scientists have found that the edge of the solar system is in the Oort Nebula, and only when it flies out of the Oort Nebula can it be regarded as really flying out of the solar system.
Scientists have calculated that it will take at least tens of thousands of years for them to completely fly out of the solar system at their speed, so for humans, they will never be able to fly out of the solar system, and humans want to fly out of the solar system. It is necessary to increase the flight speed of the spacecraft, scientists are currently actively studying warp engine technology, if this technology can be successful, then it is still possible for humans to fly out of the solar system, warp engine is a kind of antimatter drive, is the human use of space-time distortion, the singularity and the end point that human beings want to reach are constantly closer, the space between the two places will be forcibly contracted, at this time we reach the end from the starting point, subjectively speaking, it will become very close, the warp engine is different from the car engine we are usually familiar with, it is a kind of ability to distort the air around the spacecraft, so that the space in front of the spacecraft is compressed, and the space behind is expanded, and the spaceship itself is wrapped in a protective bubble that is not affected by the engine, which ensures that the ship will not be distorted.
Due to the formation of a huge space difference between the front and back of the spacecraft, a very huge gravitational field will be generated, which is equivalent to the spacecraft itself does not generate power, but distorts the surrounding space, and these spaces will flow through the spacecraft itself because they are distorted, scientists believe that space cannot be infinitely distorted, so when the space is distorted to 9.99, it is the limit of warp speed flight. This speed is 2140 times the speed of light, we can calculate, such a fast speed in the universe is what kind of experience, at a speed of light, we need 5 hours from the earth to Pluto, this speed is already very fast, but the current technology still exists in the theory, it takes a long time to realize, but human beings as the most intelligent life on the earth, human science and technology are still progressing and developing, human exploration of space will never stop, Xiaobian hopes that human beings can fly out of the solar system as soon as possible, explore a broader space, hope that this day can come as soon as possible, do you have anything to say about this？
